Variety of Sutera plant named ‘Sumsut 05’

ABSTRACT

A new and distinct  Sutera roth  plant named ‘Sumsut 05’ with violet colored double flowers and a compact growth habit.

Botanical classification: Sutera roth.

Varietal denomination: ‘Sumsut 05’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Suteraplant known by the varietal name ‘Sumsut 05’. The new variety wasdiscovered in May of 2005 in a selected breeding program in 'sGravenzande, The Netherlands. The purpose of the breeding program was todevelop double-flowering Sutera plants with a variety of colors. The newvariety is a selection from the cross of proprietary, unpatentedbreeding plants. The female parent was Seedling 1-5 and the male parentwas Seedling 2-51. The double-flowering characteristic of the newvariety is similar to its parents, but the new variety exhibits adifferent flower color and a more compact growth habit when compared toboth parents. The new variety was first asexually reproduced in July of2005 by tip cuttings in 's Gravenzande, The Netherlands. The new varietyhas been trial and field tested and has been found to retain itsdistinctive characteristics and remains true to type through successiveasexual propagations.

The following traits distinguish ‘Sumsut 05’ as a new and distinctcultivar from other Sutera varieties known to the breeder.

-   -   Double flowers; and    -   Upright and compact growth habit.

The new variety exhibits double flowers like Sutera variety ‘Sumsut 06’(U.S. Plant patent application Ser. No. 12/284,402, applied forconcurrently). However, ‘Sumsut 06’ has white flowers and a hanginggrowth habit, while ‘Sumsut 05’ has violet flowers and a compact growthhabit. The following Table 1 provides a comparative listing of botanicalcharacteristics of ‘Sumsut 05’ and ‘Sumsut 06’.

DESCRIPTION OF THE DRAWING

The accompanying photographic drawing illustrates the new variety, withthe color being as nearly true as is possible with color illustrationsof this type:

FIG. 1 is a photograph of an entire plant of the new variety.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of thenew cultivar. The data which defines these characteristics werecollected by asexual reproductions carried out in The Netherlands. Thenew variety was grown in a greenhouse in a 12 cm container and was 10weeks old when described. The color readings were taken indoors undernatural light. Color references are primarily to the R.H.S. Colour Chartof The Royal Horticultural Society of London.
